ASSIGNOB TO THE mm a PENNSYLVANIA, A CORPORATION OF .PENN- WIRE APPLYING MECHANISM FOR FOURDRINIER PAPER MAKING MACHINES 1 Application filed December 4, 1980. Serial No. 500,097.

One object of my invention is to provide suitable means for storing, supporting and applying the endless wire of a Fourdrinier paper-making machine.

A further object of the invention is to provide a means whereby the wire can be transferred from the supporting means to the machine without undue friction or damage to the wire.

A still further object of the invention is to provide a support for the wire as it is drawn from the poles at the side of the machine to its position on the Fourdrinier machine. v

The invention also relates to certain details which will be described hereinafter.

In the accompanying drawings:

Fig. 10 is a perspective view of one of the posts. Referring to the drawings: 1 is a Fourdrinier paper-making-machine, which may be of any suitable type. The particular mapoles being partly in chine shown in the drawings forms the subect of a separate application, Serial No. 497,039, filed by me on the 20th day of November, 1930. This machine consists of supporting beams 2, spaced a given distance apart, and these beams extend the full width of the machine and rest upon the usual foundation. Each supporting beam is made in the form of a single hollow casting, having an upper member 4 and a lower member 5.,

These two members are connected at one end only by a vertical member 6. The upper and lower members are spaced apart to form a throat 3 for the return run of the wire, and when the machine is in operation the outer end of the upper member is supported by a removable block 7 shown by dotted lines in Fig. 4:. This block is removed when it is necessary to withdraw an old wire and to place a new wire in position, the beams being of suificient strength to temporarily support the structure.

The Fourdrinier machine is made in two sections. 9 is a paper-making section, having rollers 10 for supporting the upper run of the wire a, and 11. is the suction box section of the machine. The lower run of the wire a, passes through the throats 3 of the supporting beams 2. 8 is the breast roll,

mounted in fixed bearings 12 on the making wire section, and 13 is the couch roll at the delivery end of the machine. The bearings 14 of the couch roll rest normally on an adjustable base 15. The base is longitudinally adjusted by means of a screw 1511 on a foundation plate 17. When the wire is to be placed upon the machine, the adjustable base 15 is moved from its normal position, shown by dotted lines in Fig. 1, to the position shown in full lines in said figure, and the bearings 14 are attached to a bracket 16 by bolts 16a, so that the couch roll is suspended from the brackets when the old wire is removed and the new wire placed in position.

' By moving the couch roll to the position shown in fulllines in Fig. 1, there is sufficient slack in'the wire a to allow the old wire to be removed from the machine and a new wire drawn onto the machine from the supporting rolls.

18, 18d are two rockers for the papermaking section of the machine. The rocker 18 is adjustably mounted on a cam shaft 19 adapted to bearings 20 secured to the beam 2 at the forward end of the machine, while the rocker 18a is mounted on a projection 21 of the suction box section of the machine. This mechanism is fully set forth and claimed in the pending application referred to above.

Located in the floor some distance from one side of the Fourdrinier'machine are a series of floor. sockets 22, and mounted in these sockets are posts 23. These posts are tubular in the present instance but they may be of any shape desired, and each post has two brackets 24 and 25, one at the upper end and one at the lower end, as clearly shown in the drawings. Each bracket has a cylindrical section 26, through which the post extends, and is fastened to the post by a set screw or other fastening device, and projecting from each bracket is a socket 27, and the socket is open at the top, so that a pole 28 can be placed inthe socket.

f On the frame of the Fourdrinier machine are a series of sockets 29 and 30, the series of sockets 29 being on that side of the machine opposite the posts, while the other sockets 30 are at the other side of the machine. These sockets are open at the top and support poles 31. It will be noticed that the po es 31 are in direct line with the poles 28, in fact they are a continuation of the poles 28, being connected by a pin and socket joint shown in Fig. 9. The pin. 32 in the present instance is secured to the poles 31 and extends into the hollow poles 28, so that the joint is suchthat there is no obstruction to the wire as it is drawn from the poles 28, to the poles 31. The lower poles 28 are on a line with the upper surface of the lower member 5 of the supporting beam 2. Other poles are in alignment with the u )pcr sur face of the wire-supporting rolls 5' Short posts are used to support the inner ends of the poles 28, which are opposite the rolls 57. In order to place the wire on the poles 28, without breaking 01' injuring the wire, I pro-- vide a truck 33, Figs. 5 and 6. which truck has a frame 34 on which is a platform 35. 36 are vcasters which allow the truck tov be freely moved from one place to another.

37 are standards projecting upwardly from the frame 34. These standards are spaced apart a greater distance than the width of themaking wire a as shown clearly in Fig. 5, and on each standard is a bracket 38, and on one arm of each bracket are two rollers 39, and the other arm 40 of. each bracket is turned up at its outer end 41 and is arranged to support the number of poles 28 within theloop of the wire, as shown in Fig. 1.

The wire is rolled-upon a spool, which con -sists of two of the poles 28 and two heads of poles, which are to be located inside of the endless making wire, as indicated in Figs. 6 and 7, and the platform 35 has a flange 44 between which and the standards 37 can be located a number of the poles 28, which are to be located outside of the endless making wire.

On the side of the Fourdrinier machine opposite the side on which the poles are mounted, is a means for drawing the wire onto the machine, and consists in the present instance of a longitudinal shaft 45 having a hand wheel 46, if the shaft is to be turned manually. The shaft is mounted in brackets 47 secured to an angle beam 48 attached to the supporting beams 2, and on the shaft are a series of drums 49, on which are wound the drawing-in ropes or belts 50 and 51.

At the free end of each rope is a snap book 52 in the present "instance, to which is attached a clamp 53, consisting in the present instance of a base plate 54 and a clamping plate 55, which are clamped to the sides of the making wire by clamp screws 56, or other suitable devices, when a wire is in position on the poles 28 at the side of the Fourdrinier machine. The clamps are secured to the edge of the wire as shown in Fig. 8, and by turning the shaft 45, the upper run of the wire and the under run of the wire are drawn simultaneously onto the Fourdrinier machine, the poles 31 supporting the upper run of wire as the wire is drawn onto the machine; the lower run of the wire restingon the upper surfaces of the lower members 5 of the supporting beams 2 and tension rollers 57 of the F ourdrinier machine. The upper surface of the member 5 may be sheathed with copper plates 58 to prevent chafing of the wires. 1

Then a wire is to be replaced, the old wire is removed from the machine in any suitable manner. has been previously mounted, in the manner shown in Figs. 5, 6 and 7, is removed from the store'room and the posts 23 are mounted in their sockets 22. Then the truck is moved longitudinally along the-side of the machine between the posts 23 and the machine, and one of the poles 28 is placed in position on the upper socket bracket 24 of the first post 23, andis connected alignment with the pole 31 on the machine and another pole 28 uppersurface'of the lower-member 5 of the- The truck on which the new wire first sup orting beam 2. Then as the truck is move forward and other poles are placed in position, as shown in Fig. 1, so as to properly support the wire, and as the truck continues its movement in the direction of the arrow, Fig. 1, the wire is hung on the poles until the last pole is reached, the wire encircling the eouch roll 13. Then the truck is removed.

In the present instance six posts are shown but the number of osts will depend upon the length of the Four rinier machine. After the wire has been placed on the several poles, as

shown in Fig. 2, then the clamps 53- are secured to the edge of the wire nearest the Fourdrinier machine, and the shaft 45 turned by the hand wheel 46or other suitable appliance and the upper and lower runs of the wire are simultaneously drawn into the machine, the. breast roll and the couch roll being in the position shown in full lines in Fig.

2, allowing the wire to freely pass over these rolls. When the wire is in position in the machine, the poles 31 are removed and the blocks 7 are placed in position under the overhanging portion 4 of the beam and the poles 28 are removed, and the posts 23 withdrawn from their sockets. The empty truck is returned to the storeroom, where another wire can be mounted thereon for future use.

In some instances where there is suflicient space, the posts 23 may be permanently located in the floor but in most paper-making mills the space is limited and it is desirable to make the posts 23 removable so as to al: low a clear floor space.

At one side of the machine is the shaking mechanism 60, for the paper-making section of the machine. This mechanism consists in the present instance of three standards 61, having levers 62 connecting the shaking mechanism on each post with the paper-making section of the machine. The shaking mechanism is driven by a motor 63 in the present instance, geared to a shaft 64 common to all the standards. This shaking mechanism forms no part of the present in-' vention. It is fully described and claimed in the co-pending application referred to above. I

In place of the short posts at the inner side of the poles 28, which are opposite therolls 5,7, brackets may be provided on the frame, which support the rolls 57', without departing from the invention, and in some instances the poles may be spaced in such a manner that they will be located between the supporting beams and the rolls 57, and suitable supporting posts may be used to carry these poles.

In some instances the pin socket joint which connects the two poles, as shown in Fig. 9, may be omitted and the bracket 29 may be extended so as to carry both poles, as shown by dotted lines in Fig. 4. The rear bracket forms an abutment for the poles, as

. rollreturned to its normal dotted lines in Fig. 1, and the tension rolls.

the machine.

By the above descri tion it will be seen that the making wire can e readily mounted on shown in Fig. 4,'as the wire is drawn onto the Fourdrinier machine without buckling or manner, as thereside of the machine for ready access-to the machine at any time, and by locating poles on the upper portion of the machine the u per run of the'wire can be drawn t rom t e poles at the side of the machine to a position in the machine without interference, and

" when the wire is in position, then the poles above the machine areremoved and the couch position shown by 57 are raised so as to sion on the wire.
